It has been a while since we have last CPU mined a crypto coin that only has a CPU miner and not a GPU or ASIC and uses a new crypto algorithm, it has been a while since we have used the cpuminer-opt as well. So why not get back to it and put some stress on your processor for mining using the latest cpuminer-opt 3.8.4 (download) and mine WAVI coins (Bitcointalk announcement) that use the new yescryptr32 algorithm.

If you are interested in what kind of performance you can expect mining this algorithm with a CPU, here is a reference for you. An Intel Core i7 6850K (6-cores at 3.6 GHz + HT) does around 635 H/s in the yescryptr32 algorithm without overclock of the processor. A processor like the commonly used Intel Celeron G1840 (Dual Core at 2.8 GHz) manages to get around 110 H/s in terms of hashrate when mining yescryptr32. If you try mining WAVI coins with a different processor feel free to share your performance results in the comments below…

We haven’t paid a lot of attention lately to alternative crypto coins that are mined only with CPU with no GPU, FPGA or ASIC miners, so we’ve decided to check what is going on with Coin Magi (XMG) as we haven’t been following it actively the last few months. Coin Magi is a PoW and PoS coin that is currently being traded for a little over 2000 satoshi per coin, it is being traded on multiple altcoin exchanges including some of the largest ones, though the trade volume at the moment is pretty low and there are multiple pools where you can mine the coin if you do have some spare CPU power available and you are wondering what to mine.

Coin Magi (XMG) uses the M7M algorithm and besides CPU mining and staking coins you can also rent mining rigs at the Mining Rig Rentals service. Last year we have tested the most up to date miner available for XMG – the Wolf0 m7m v2 cpuminer on an Intel Core i7 5820k CPU and now we have retested again in order to compare it with a more recent release in the form of a dedicated m-minerd for XMG (source) that is based on Wolf0’s code. The 32-bit version is significantly slower, so we do recommend to go for the 64-bit miner for best performance, but interestingly enough we are getting slightly less performance for, the new miner. The advantage that the new m-minerd miner for the M7M algorithm has an option for that allows you to set the percentage of CPU usage you want the miner to take.

Intel Core i7 5820k (6C 12T) CPU:
– Wolf0 minerd 64-bit – 122 KHS
– m-minerd 32-bit – 64 KHS
– m-minerd 64-bit – 119 KHS

Even though most people are either GPU mining or using specialized ASIC miners for most crypto coins, there are still some that are only CPU mineable or at least are worth CPU mining even if they do come with a GPU miner as well. Since we are getting questions what crypto coin to mine if you have some spare CPU power available, we have compiled a short list of coins that you might want to check out. Do note that with a single CPU you will most likely not earn much mining any CPU coin, but if you have multiple CPUs available along with free electricity the outcome might be better…

Crypto coins to check for CPU mining:
Boolberry (BBR)
Coin Magi (XMG)
Cryptonite (XCN)
DigitalNote (XDN)
Monero (XMR)

The list is alphabetically ordered are there are a few other CPU coins available as well besides the ones listed above, many of these based on the CryptoNight algorithm used by XMR and some others as well, so if you are interested you can dig a bit more into the alternatives. Alternatively you can look for new coin launches that only come with CPU mining, these can be profitable to mine initially as well.
